G RATE-BAR.
SPECIFICATION forming part of Letters Patent No. 390,902, dated October 9, 1888.
Application tiled December $22, 1887. Serial No. 258,657. (No model.)
To all whom t may concern:
Be it known that l, OWEN REILLY, a citizen of the United States, residing at New York, count-y and State of New York, have invented certain new and useful Improvements in Grate- Bars, of which the following is a speciiication.
This invention relates to shaking-grates, such as is shown in the United States Letters Patent No. 126,060, dated April 23, 1872, in which the gratebars are supported on transverse crank-bearing bars in such a manner that when one of said bearing-bars is rocked the alternate grate-bars are vcaused to move in opposite directions.
This invention embraces improvements in the grate-bars and in the transverse crankbearing bars, whereby the gratebars are less liable to warp and are held in operative position without any parts of the adjacent bars touching, as will be hereinafter fully described, reference being had to the accompanying drawings, forming' part of this specification, in which- Figure l is a plan view of a furnace-grate embodying my invention. Fig. 2 is an end view of the same with some of the gratebars partly broken away. Fig. 3 is a longitudinal Fig. 4 is a longitudinal section on the line yy, Figs. l and 5. Fig. 5 is a transverse section of one cf the outside bearing grate-bars, and Fig. 6 is a transverse section of one of the shaking grate-bars.
The transverse crank-bearing bars c and b are in their general construction similar to those shown and described in the before-mentioned Letters Patent, their novelty consisting in the teeth c and d, cast integral therewith, arranged in the center of the bearingsurfaces which support the shaking grate-bars e and f.
The curved bearing-surfaces of the shaking bars e andf, which rest on the crank-bearing surfaces of the transverse bars c and b, are provided with recesses to receive the teeth d and c of the transverse bars a and b, whereby the said bars e and f are controlled and moved longitudinally by the bars a and b, when one or both of them is or are caused to rock on the edges g and h, and the bars e and f are laterally held in position, so as to maintain uniform spaces between them, thereby avoiding the necessity of using spacing-lugs on their sides and allowing them free scope of action without any side friction, even though they should warp considerably in a lateral direction.
To prevent as much as possible the side warping of the grate-bars, I make the said bars e and f donble,with their outside walls straight and without any lugs or projections whatever, and connect the two parts of the bars together at their ends where they rest on the rocking bars a and b, and at their central parts at one or more places, according to the length of the bars, as shown, by connecting-piecest and j, which, with the end connections, are cast integral with the two longitudinal parts of the bars. The upper edges of the two longitudinal parts of the bars e and f are provided with teeth 7c le, angularly arranged on their top surfaces relatively to the length of the bars. These teeth le k project over the air-space between the two longitudinal parts of the bars, and their sides are inclined and meet on aline at an angle to the vertical walls of the bars, thus forming between them angular inclined grooves, as clearly shown at Figs. 3 and 6.
The supporting grate-bars Z and m are provided with openings at their ends, in which the rocking edges ot' the bearing-bars a and b rest inthe usual manner. These bars Z and m, to facilitate casting, I make in two parts, and cast in lugs n u on one of the parts short pieces of wrought-iron pipe o o, and in the other parts cast corresponding holes. After these parts have been placed together, the ends of the wrought-iron pipes are set or riveted over, as shown at Fig. 5. This method of connecting the two parts of the bars together is very efficacious, and embraces simple, cheap, and strong means for the purpose. The teeth p p on the tops of the bars Z and m are in their general construction similar to the teeth on the bars e andf,- but they are set squarely on the bars.
Having now described my invention, whatI claim, and desire to secure by Letters Patent, 1s-
